Disposable medicine applicator

Claim 2

A disposable applicator for facilitating the injection of a desired dosage of a gel-like medicine into a body cavity after the application is filled with the desired dosage of the medicine, said disposable applicator comprising: a barrel having a tubular shape and comprising a plurality of spirally wound paper layers, said barrel having opposing first and second open ends, the first open end of said barrel for permitting the passage of a gel-like medicine therethrough to fill said barrel and for being inserted into a body cavity to inject the medicine into the body cavity from the thus filled barrel, the first open end of said barrel having an inturned lip to facilitate insertion into the body cavity; a plunger slidably positioned within said barrel and movable relative to said barrel between an unfilled position wherein said barrel contains no medicine and a filled position wherein said barrel contains a desired dosage of medicine, said plunger having a tubular shape and comprising a plurality of spirally wound paper layers, said plunger having opposing first and second ends, the first end of said plunger being closed to serve as the working end of the plunger for ejecting the medicine from said barrel as said plunger is moved from the filled position to the unfilled position, the second end of said plunger including inwardly crimped portions to substantially close the second end of said plunger to thereby prevent the inadvertent or accidental filling with medicine of said plunger rather than said barrel, the length of said plunger being greater than the length of said barrel and of such length that said inwardly crimped portions on said second end are always exposed irrespective of the barrel being filled with medicine or unfilled; and indicia means on a predetermined outer surface portion of said plunger for indicating that said barrel contains the desired dosage of medicine when said plunger extends outwardly from the second end of said barrel in the filled position thereby exposing said indicia means.

Claim 3

A disposable applicator according to claim 1 wherein said plunger has a circular cross-section and, wherein said inwardly crimped portions of said plunger and portions adjacent thereto are contained within an imaginary circle as defined by said plunger.

Claim 4

A disposable applicator according to claim 1 wherein said inwardly crimped portions of said plunger extend lengthwise along a portion of said plunger and define a star pattern in end view.

Claim 5

A disposable applicator according to claim 1 wherein said inwardly crimped portions of said plunger extend lengthwise along a portion of said plunger and define a saddle pattern in end view.

Claim 6

A disposable applicator according to claim 1 wherein said indicia means comprises ink and wherein said ink is of a type approved for direct human contact.

Claim 7

A disposable applicator according to claim 1 wherein said paper layers of said barrel and said plunger are of a type approved for direct human contact.

Claim 8

A package for facilitating the injection of a desired number of successive dosages of a gel-like medicine into a body cavity, said package comprising: a container having a tubular shape with opposing first and second ends, the first end of said container being closed and the second end of said container being open; a removable closure cap covering the second end of said container; and a predetermined number of disposable applicators positioned within said container corresponding to a number of desired dosages of a medicine, each of said disposable applicators comprising a barrel having a tubular shape and comprising a plurality of spirally wound paper layers, said barrel having opposing first and second open ends, the first open end of said barrel for permitting the passage of a gel-like medicine therethrough to fill said barrel and for being inserted into a body cavity to inject the medicine into the body cavity from the thus filled barrel, the first open end of said barrel having an inturned lip to facilitate insertion into the body cavity; a plunger slidably positioned within said barrel and movable relative to said barrel between an unfilled position wherein said barrel contains no medicine and a filled position wherein said barrel contains a desired dosage of medicine, said plunger having a tubular shape and comprising a plurality of spirally wound paper layers, said plunger having opposing first and second ends, the first end of said plunger being closed to serve as the working end of the plunger for ejecting the medicine from said barrel as said plunger is moved from the filled position to the unfilled position, the second end of said plunger including inwardly crimped portions to substantially close the second end of said plunger to thereby prevent the inadvertent or accidental filling with medicine of said plunger rather than said barrel, the length of said plunger being greater than the length of said barrel and of such length that said inwardly crimped portions on said second end are always exposed irrespective of the barrel being unfilled or filled with medicine; and indicia means on a predetermined outer surface portion of said plunger for indicating that said barrel contains the desired dosage of medicine when said plunger extends outwardly from the second end of said barrel in the filled position thereby exposing said indicia means.

Claim 9

A package for facilitating the injection of a desired number of successive dosages of a gel-like medicine into a body cavity, said package comprising: a container having a tubular shape with opposing first and second ends, the first end of said container being closed and the second end of said container being open; a removable closure cap covering the second end of said container; and a predetermined number of disposable applicators positioned within said container corresponding to a number of desired dosages of a medicine, each of said disposable applicators comprising a barrel having a tubular shape and comprising a plurality of spirally wound paper layers, said barrel having opposing first and second open ends, the first open end of said barrel for permitting the passage of a gel-like medicine therethrough to fill said barrel and for being inserted into a body cavity to inject the medicine into the body cavity from the thus filled barrel, the first open end of said barrel having an inturned lip to facilitate insertion into the body cavity; a plunger slidably positioned within said barrel and movable relative to said barrel between an unfilled position wherein said barrel contains no medicine and a filled position wherein said barrel contains a desired dosage of medicine, said plunger having a tubular shape and comprising a plurality of spirally wound paper layers, said plunger having opposing first and second ends, the first end of said plunger being closed to serve as the working end of the plunger for ejecting the medicine from said barrel as said plunger is moved from the filled position to the unfilled position, the second end of said plunger including inwardly crimped portions to substantially close the second end of said plunger to thereby prevent the inadvertent or accidental filling with medicine of said plunger rather than said barrel, the length of said plunger being greater than the length of said barrel and of such length that said inwardly crimped portions on said second end are always exposed irrespective of the barrel being unfilled or filled with medicine; and indicia means on a predetermined outer surface portion of said plunger for indicating that said barrel contains the desired dosage of medicine when said plunger extends outwardly from the second end of said barrel in the filled position thereby exposing said indicia means.

Claim 10

A package according to claim 7 wherein said container comprises a plurality of spirally wound paper layers.

Claim 11

A package according to claim 7 wherein each of said disposable applicators has a predetermined length substantially equal to an interior length of said container so that said disposable applicators are positioned within said container so as to prevent undesired lengthwise movement of said applicators within said container.

Claim 12

A package according to claim 7 wherein the predetermined number of disposable applicators is seven, and wherein said container has a circular interior cross-section with a diameter substantially equal to three times a diameter of said disposable applicators so that said seven disposable applicators are positioned within said container to prevent undesired radial movement of said applicators within said container.
